Abstract

The transport properties of TlI and the system AgI-TlI were investigated by measuring the electrical conductivity, sigma, and the electronic and ionic transport numbers. A particularly high electronic conductivity was detected in beta-TlI, while the alpha phase showed a predominant anionic contribution, as in TlCl and TlBr. The intermediate compounds, AgTl 2I 3 and AgTlI 2 , are silver ion conductors, but they exhibit low sigma values. A comparison with other polyiodides, with a high silver ion conductivity, is suggested on the basis of the crystal bond ionicity.
